Abstract

The  purpose  of this  study is to investigate the  feasibility of offline fault  location and  state of health technologies for airport series circuits  used  to provide  power  to light fixtures  on the  runway.  In current  series  circuits, only  some ground  faults  can  be detected and  no automated fault  location  or state of health features are available. Fault location is currently performed with an isolation tester and a”divide and conquer”-methodology which is very time consuming and personnel intensive.
